9 cloifns. (OL 6112) particulafly, it is intended that the watef paSs ing ovef an opening in the bottoIn of o un1e be scoo ed off and de1ivered downwardl towardS the fufrow in positively controlled streaInS, 1fd ditionany, it is intended to pfovide for the SWif1- in of the Scoopedoff aInounts of vvafeT So that the energy thereof is dissipated, the water theTe aftef being dropped fe1tive1y quietly to the gfound father than be diSchafged in 9 Strong, erosive streaIn.

nothef objeot of the invention iB the provi sion of aJ nufne, pfeferably foffflea. of Sllitable Sheet nlateriaL and having sefies of diSoharge openingS Spaced aloT1g the 1ongth theroof, the

In order `to revent leakage through the unuSed botton1 openings, it iS intended that the bottofn of the flunle be pfovided With an upstanding bliStef iIn Inediately upstfeaIn of each bottoIn opening so that the f111Ine strean1 vvi11 norn1ally be deflected up nd over the lbotton1 opening, and Wi11 not pass downWardly through the opening unless a scoop of the like deflecting elenlent is positioned in the flun1e streaTn to defleot SoIne of the paSS- ing water downwafdly through the openingfet another object is to `pfovide a delivery Scoop having a deeotof adapted to project up vvardly thfough an opening in a ffuIne bottoIn, and So arranged that the angle of the deectof Inay be Seleotively Inaintained, and So that the effeotive extent of the defiectof Inay be se1e oted, thus to control the an1ounf of water thereby de ffected downWafdly through the flunle opening. It iS also intended to pfovide for the eaSy attaoh Inent, detaohInent of the sooop.
